Aeration is one of the most significant improvements that can be made to ensure water quality. Aeration mixes water with energy and exposes the water to the atmosphere for an exchange of gases that will increase oxygen levels and off-gas other gasses that would be limiting to the biology of the pond or lake. Aeration also mixes the water which evenly distributes temperature, pH, and nutrients in the pond. Cooler surface temperatures reduce the occurrence of nuisance algae. The consistent environment benefits fish greatly for increased growth, health, and vigor.
There are several different types of aeration including high-volume surface aerators, aerating fountains, decorative fountains, and diffused aeration. These are all tools to help you meet your goal of aerating the pond or lake while including other considerations such as the desire for a display, a serene view, electrical safety, and energy usage.
